Advanced material information (AMI) collection system file synchronization method

Abstract

An advanced material information (AMI) collection system file synchronization method comprises the following steps that when being detected by a terminal, an ammeter synchronization event is initiatively transmitted to a main station, when the main station discovers information needing the file synchronization, a corresponding ammeter synchronization event flow is triggered, the terminal replies a message containing the ammeter synchronization event to the main station, the main station inputs a main station ammeter file or deletes the main station ammeter file and transmits an ammeter mapping message to the terminal according to the message replied by the terminal, the corresponding ammeter synchronization event information is added into a terminal file after the terminal receives the mapping message, so that the synchronization of the main station and the terminal ammeter file information of device language message specification (DLMS) can be realized. Due to the adoption of the method, the problem that the file synchronization between the main station and the terminal cannot be realized under the situation that a collection system marketing interface is not adopted can be solved; and moreover, the entire flow is only triggered after the initiative report of the ammeter synchronization event of the terminal, the updating flow of the ammeter synchronization event can be automatically completed, the file synchronization operation flow is simplified, and convenience for maintaining the consistence of the main station and the terminal in real time can be realized.

Description

technical field [0001] The invention relates to a method for synchronizing files by adopting a DLMS standard AMI collection system, which belongs to the technical field of electric power automation system and communication. Background technique [0002] AMI is a complete network processing system used to measure, collect, store, analyze and apply user electricity consumption information. It consists of a smart meter installed at the user end, a measurement data management system located in the power company and a communication system connecting them. . Among them, AMI is the key system of the smart grid, and the terminal, as an important on-site information collection device in the AMI collection system, is generally installed in remote outdoor places. Most of the terminal and the meter use PLC for communication. As we all know, The PLC communication is not stable enough, and the communication effect is easily disturbed by external factors. Therefore, there is no way to re...

Among them, AMI is the key system of the smart grid, and the terminal, as an important on-site information collection device in the AMI collection system, is generally installed in remote outdoor places. Most of the terminal and the meter use PLC for communication. As we all know, The PLC communication is not stable enough, and the communication effect is easily disturbed by external factors. Therefore, there is no way to read some meter data in the meter files of the main station. The file entry at the main station is not efficient enough, so the electric meter files of the terminal and the main station must have the ability to automatically synchronize real-time files

However, the current domestic acquisition system collects the main station’s file entry through the electricity marketing interface. The terminal cannot automatically enter the detected new electric meter file into the terminal, and the main station cannot automatically enter the file entry of the terminal’s detected electric meter information. The file information of the electric meter cannot be automatically and timely synchronized with the main station, which is not conducive to the timeliness and effectiveness of the AMI collection system for collecting electric meter information, and is not conducive to the remote maintenance of the terminal file by the main station
